AWS Classroom Series – 28/Oct/2020

How will my network know which ip address to allocate?

• Every network when created requires a input of network range
• Network will take help of DHCP to assign an ip address to the machine connected

What should be ip address range which i should give while creating network

• Networks are of two types
  • Public Network
  • Private Network
• We are using ipv4 (32 bit addresses)
• Ipv4 has some reservations for private network
  • 10.0.0.0 to 10.255.255.255
  • 172.16.0.0 to 172.31.255.255
  • 192.168.0.0 to 192.168.255.255
• In AWS we create private networks.

Scenario-1:

• QT has a lab-1 and lab-2 in the office and then there is workplace.
  • lab-1 has 200 devices
  • lab-2 has 200 devices
  • In the workplace there will 200 people working
• How do i design a private network for the organization
• Steps:
  • Design a organization network
  • With in this network create subnet (sub-networks) for
    • lab-1
    • lab-2
    • workplace
  • QT has 600 devices at this moment
    • lab-1, lab-2 and workplace have 200 devices
• Implementation:
  • Lets create a QT Network with range 192.168.0.0 to 192.168.255.255 => 192.168.x.x => 16 => 2^16 => 65535

Scenario-2

• LT has a workplace where there are 1000 employees and a lab with 2000 devices. Design a private network

Scenario-3
